Let's just admit this on the front end...most of us don't know how secure our computers are when we're logged onto a public Wi-Fi network. If you're like me you can't help but think it's not really a big deal. That's the same thing David Pogue of the New York Times thought until recently. He decided to meet someone who could tell him just how much (if any) information someone could see when we're connected to public, unsecured Wi-Fi networks. You'll see in his post that he's changed his mind. I think I have too. Like David, I don't know that it's really going to change much about my actual practices but now I'm much more aware than I was prior to this post.
